👷 A must-have for on-site electrical safety managers and facility teams: the 'KEC Electrical Calculator'
"Will the circuit breaker trip if I connect another piece of equipment?"
"I'm not sure if the circuit breaker will be safe even if I expand the installation?"
The KEC Electrical Calculator was created to address these concerns for facility managers responsible for powering buildings and factories. It provides the easiest and most accurate calculations of complex Korean Electrical Code (KEC) formulas on mobile, increasing work efficiency.
Notably, to ensure **'complete trust'** in our calculation results, we transparently disclosed the **core calculation logic (engine)** at the heart of the app on GitHub. Anyone can verify the code, making it the most honest and transparent electrical calculator in Korea.

### 🔥 Why the 'KEC Electrical Calculator'?
**1. Transparent Logic Disclosure (Industry First)**
Unlike other closed calculator apps, we don't hide our calculation algorithms. You can visually verify the accuracy of the formulas through the GitHub open source.
👉 **View the source code:** https://github.com/OpenKEC/kec-safety-calculator-core
**2. 'Expansion Review' Optimized for Facility Management (New!)**
Have you ever been frustrated when adding air conditioners or new equipment to an existing distribution panel?
Now, simply enter your information in the app. When adding equipment, it automatically determines whether the main circuit breaker and cables can withstand the load and pose a risk.
**3. Fully Compliant with the Korean Electrical Installation Code (KEC)**
The app fully complies with the latest KEC regulations, not the outdated internal wiring regulations.
- Permissible current compensation based on construction method (A1~G) and wiring type
- Automatically applies reduction factors based on ambient temperature and conductor type
- Precise calculations that consider voltage drop rates and mechanical strength
**4. Design Optimized for Field Use**
Designed for easy visibility even in dark machine rooms or in front of distribution panels. - Large buttons for easy pressing even with gloves
- Intuitive results screen that displays only the necessary results at a glance

### ⚡ Key Feature Details
✅ **Distribution Board Expansion Capacity Review**
- When adding additional loads, the app automatically determines the appropriateness of the main/branch circuit breaker capacity and cable size, indicating whether it is "safe" or "dangerous."
✅ **Automatic Wire Size Selection**
- When entering load capacity (kW), the app recommends the optimal wire size based on KEC regulations, considering the construction method and wiring length.
✅ **Calculate Circuit Breaker Capacity**
- Select the appropriate circuit breaker (MCCB/ELB) size for your site, considering both overload protection and short-circuit current conditions.
✅ **Voltage Drop and Allowable Current Inquiry**
- Calculate the voltage drop rate (%) based on line length and instantly check the allowable current for each cable type without having to search through complex tables.

### 👨🔧 Highly recommended for:
- **Building/Factory Facility Management Team (FMS/Public Works Team):** Those who need immediate load capacity reviews when installing new equipment or changing layouts.
- **Electrical Safety Manager:** Those who perform regular inspections and ad-hoc safety reviews.
- **Electrical Workers and Interior Contractors:** Those who need on-site quotes and material selection.
- **Electrical Designers and Supervisors:** Those who need cross-checking to ensure design values comply with KEC regulations.
